PREFACE 


This  book  contains  miscellaneous  hydraulic  information, 
useful  engineering  tables  and  a  complete  table  showing  the 
Flow  of  Water  in  WOOD  PIPES  of  various  sizes  and  under 
varying  heads.  It  is  designed  not  only  for  the  use  of  the 
Engineer,  but  is  also  intended  for  a  handy  reference  book  for 
the  Mayor  and  his  Council,  the  Water  Superintendent,  the 
Irrigator,  the  Miner,  in  fact  for  anyone  who  has  occasion  to 
divert  water  from  its  natural  channel  for  the  purpose  of  domestic 
uses,  power  plants,  irrigation,  etc. 

As  a  means  of  conveying  water  for  all  purposes,  whether 
the  quantity  be  merely  a  few  gallons  a  minute  or  hundreds  of 
cubic  feet  per  second,  WOOD  PIPE  is  now  conceded  by  advanced 
engineers  and  experienced  laymen  to  be  an  engineering  and 
economic  success. 

The  flow  of  water  in  WOOD  PIPE  is  greater,  size  for  size, 
than  in  pipe  constructed  of  any  other  kind  of  material. 

The  flow  tables  herein  given  are  based  as  far  as  possible 
on  results  obtained  by  various  experiments  and  may  be  assumed 
to  be  as  nearly  correct  as  is  required  in  a  calculation  of  this 
kind. 

We  have  endeavored  to  make  the  tables  in  this  book  in 
such  simple  form  that  they  can  be  readily  understood,  and  in 
order  to  assist  in  such  an  understanding,  examples  and  ex- 
planations are  given  where  necessary.

TEN  REASONS  FOR  USING  WOOD  PIPE 

1.  It  is  preserved  by  water  and  not  rusted  or  corroded 
by  it. 

2.  It  is  not  corroded  by  sulphur,  salt  or  mineral  water  and 
fumes. 

3.  It  is  not  destroyed  by  acids  or  salts. 

4.  Its  carrying  capacity  is  20%  greater  than  cast  iron 
pipe,  and  remains  constant  while  metal  pipe  decreases  with 
age. 

5.  It  does  not  taint  or  affect  fluids  going  through  it. 

6.  It  does  not  burst  when  frozen.    The  elasticity  of  the 
wood  prevents  bursting. 

7.  It  requires  less  labor  and  experience  to  lay  in  place 
than  metal  pipe. 

8.  It  can  be  laid  in  shallower  ditches  than  metal  pipe,  for 
it  is  not  easily  affected  by  frosts. 

9.  It  is  cheaper  than  steel,  wrought  iron  or  cast  iron  pipe. 

10.     Its  durability  exceeds  steel  or  wrought  iron  pipe,  and  is 
classed  with  cast  iron  pipe. 


We  manufacture  Pipe  and  Tanks  from  both  Douglas  Fir 
and  Redwood  lumber,  making  a  specialty  of  Fir  at  our  Port- 
land factory  and  Redwood  at  our  San  Francisco  and  Los

"A  WORD  TO  ENGINEERS" 

In  locating  wood  pipe  lines  for  irrigation,  power  plants, 
city  water  systems,  etc.,  there  are  several  points  that  it  would 
be  well  for  the  engineer  to  consider  carefully. 

First — Pipe  designed  for  heavy  pressure  requires  a  greater 
amount  of  metal  than  low  pressure  pipe  thereby  increasing 
the  cost;  but,  in  running  out  a  ditch  line,  it  is  frequently  more 
economical  to  run  across  a  valley,  gulley  or  even  a  slight 
depression  with  an  inverted  syphon  rather  than  follow  the 
contour  with  a  ditch. 

Second — As  has  been  shown  by  years  of  experience,  the  life 
of  wood  pipe  is  materially  prolonged  by  the  saturation  of  the 
staves,  we,  therefore,  deem  it  good  engineering  practice,  in 
all  cases  where  conditions  will  permit,  to  drop  the  grade  of 
the  pipe  as  quickly  as  possible  from  the  intake  to  a  grade  of 
25  feet,  or  nearly,  beneath  the  hydraulic  grade  line.  This 
insures  a  pipe  constantly  full  of  water  and  the  saturation  of 
the  top  staves  as  well  as  the  bottom,  under  pressure,  while  at 
the  same  time  it  does  not  affect  the  quantity  of  metal  and 
therefore  does  not  increase  the  cost. 

Third — At  all  summits  in  the  pipe  line  air  valves,  or  vents, 
should  be  placed.  These  may  consist  of  automatic  devices, 
a  number  of  which  are  on  the  market  and  have  proven  satis- 
factory; or,  if  the  pipe  location  is  on  side  hill,  a  pipe  of  sufficient 
diameter  may  be  laid  up  the  hill  to  an  elevation  slightly  above 
the  hydraulic  grade  line,  or,  where  necessary,  above  the  line 
of  static  pressure. 

It  is  especially  important  that  an  air  vent  be  placed  at  the 
point  where  the  pipe  drops  with  increased  gradient  to  reservoir 
or  power  plant  so  that,  in  case  more  water  be  drawn  off  at  the 
outlet  than  the  light  gradient  above  can  supply,  a  vacuum 
will  not  be  caused  and  collapse  of  the  pipe  will  thus  be  averted. 

Fourth — In  determining  the  pressure  head  for  which  a  wood 
pipe  shall  be  banded,  ample  allowance  should  be  made  for 
water  hammer  or  surge  due  to  pumping  or  rapid  closing  of 
valves.  The  factor  of  safety  should  be  based  on  the  maximum 


PACIFIC  TANK  &  PIPE  COMPANY  9 

pressure  to  which  the  pipe  can  possibly  be  subjected.  For 
example — a  pumping  line  having  a  45-foot  lift  or  static  head, 
may  have  a  friction  head  of  15  feet  and  a  possible  additional 
head  of  20  feet  due  to  water  hammer.  The  pipe  in  this  case 
should  be  banded  for  80-foot  head. 

Fifth— In  drawing  specifications  remember  that  manu- 
facturers have  standard  forms  of  construction  that  have  been 
approved  by  engineers  of  ability  and  great  experience.  A 
deviation  from  standard  means,  usually,  an  increased  cost  and, 
most  frequently,  a  product  of  inferior  quality. 

We  procure  for  our  pipe  the  best  lumber  that  grows  and  is 
handled  in  the  lumber  market.  The  most  carefully  and  rigidly 
drawn  specifications  cannot  improve  its  quality. 

The  same  is  true  of  our  other  materials,  steel  rods,  galvan- 
ized wire,  cast  iron,  etc.  They  are  manufactured  of  the  best 
quality  of  raw  material  and  are  finished  in  the  most  suitable 
manner  for  the  purpose  for  which  they  are  intended. 

As  specifications  on  all  materials  are  more  or  less  subject 
to  change  we  do  not  print  them  in  this  book,  but  for  any  specific 
project  we  will  gladly  furnish  specifications  upon  request. 

Sixth— While  the  PACIFIC  TANK  &  PIPE  COMPANY  is 
essentially  a  manufacturing  organization,  we  do,  however,  in 
order  to  insure  satisfaction  to  our  customers,  undertake  to 
construct  Continuous  Stave  Pipe  in  place  or  to  lay  Machine 
Banded  Pipe  in  place  under  certain  conditions,  which  are  as 
follows: 

The  purchaser  agrees  to  unload  material  from 
the  cars,  sort,  haul  and  distribute  the  same  along 
the  line  of  the  trench  in  the  manner  directed  by 
us,  do  all  trenching,  backfilling,  furnish  and  erect 
all  trestles  or  structures  other  than  pipe. 

We  furnish  all  material  f.  o.  b.  cars  at  point  of 
delivery  and  construct  the  pipe  in  place  under 
contract,  or  furnish  the  material  as  above  and 
an  experienced  man  to  superintend  the  construc- 
tion work  at  a  price  per  diem.

DEFINITIONS 

For  illustration  of  definitions  see  cuts  on  opposite  page. 

The  following  definitions  are  not,  on  account  of  space, 
sufficiently  comprehensive  to  satisfy  the  requirements  of  the 
practicing  engineer.  They  will,  however,  be  of  interest  to 
those  who  have  neither  the  time  nor  the  inclination  to  study, 
more  deeply,  the  mysteries  of  hydraulics. 

HEAD. — The  word  Head  as  applied  to  pipe  lines  has  a 
variety  of  meanings  and  is  sometimes  carelessly  used  by 
engineers  and  laymen.  The  several  meanings  are  classified 
and  described  in  the  following  ways: 

STATIC  HEAD.— The  Static  Head  is  the  difference  in 
elevation  between  the  surface  of  the  water  at  the  intake  and 
the  elevation  of  any  given  point  in  the  pipe  line.  From  this 
vertical  measurement,  which  is  usually  stated  in  feet,  is  ob- 
tained the  internal  pressure  per  square  inch  which  is  herein- 
after described  under  the  title  of  Pressure. 

TOTAL  HEAD.— The  Total  Head  (sometimes  called  Total 
Fall)  is  the  difference  in  elevation  between  the  water  at  the 
intake  and  the  surface  of  the  water  at  the  outlet  and,  in  con- 
nection with  gravity  lines  with  an  open  end  discharge,  is 
the  sum  of  three  items,  viz.:  Friction  Head,  Velocity  Head 
and  Entrance  Head,  which  are  defined  in  order. 

FRICTION  HEAD.— Assuming  a  gravity  line  discharging 
into  a  reservoir  with  the  discharge  end  under  the  surface  of 
the  water,  the  Friction  Head  is  the  difference  in  elevation 
between  the  surface  of  the  water  at  the  intake  and  the  elevation 
of  the  water  at  the  outlet  after  the  sum  of  the  Velocity  Head 
and  the  Entrance  Head  shall  have  been  deducted.  Should  the 
discharge  pipe  be  above  the  surface  of  the  water  then  the 
center  of  the  discharge  end  should  be  considered  rather  than 
the  surface  of  the  water  in  the  reservoir. 

Friction  Head,  also  known  as  Loss  due  to  Friction,  is  the 
difference  in  pressure  (resolved  into  feet  head)  between  any 


12  PACIFIC  TANK  &  PIPE  COMPANY 

two  given  points  in  a  continuous  line  of  pipe,  the  difference  in 
pressure  being  due  to  the  friction  between  the  water  and  the 
interior  surface  of  the  pipe. 

From  the  Friction  Head  is  obtained  the  slope  governing 
the  flow  of  water  in  the  pipe.  This  slope  will  be  recognized 
under  a  definition  given  later  as  the  Hydraulic  Gradient. 

VELOCITY  HEAD.— The  Velocity  Head  is  a  distance 
measured  down  from  the  surface  of  the  water  at  the  intake 
and  is  determined  by  the  law  of  falling  bodies.  In  order  that 
the  water  in  the  pipe  may  flow  with  sufficient  velocity  to 
maintain  the  discharge  for  which  it  is  designed  a  certain  dis- 
tance, or  fall  through  space,  must  be  utilized  by  the  law  of 
gravity  in  obtaining  that  velocity. 

ENTRANCE  HEAD.— The  Entrance  Head  is  generally 
assumed  to  be  half  of  the  Velocity  Head  and  is  due  to  the 
resistance  caused  by  the  eddies  produced  by  the  water  entering 
the  end  of  the  pipe.  This  may  be  to  a  great  extent  overcome 
by  using  an  enlarged  or  funnel  shaped  intake,  but  in  most  cases 
the  velocity  is  not  sufficiently  great  to  make  this  item  of 
moment.  Especially  is  this  true  of  long  pipe  lines  where  with 
a  comparatively  low  velocity  both  the  Entrance  Head  and 
the  Velocity  Head  are  so  small  that  they  can  be  omitted  from 
consideration. 

PRESSURE  HEAD. — The  Pressure  Head  is  the  difference 
in  elevation  between  the  surface  of  any  confined  body  of  water 
and  any  point  in  the  container  where  it  may  be  desired  to 
ascertain  the  pressure.  After  the  Pressure  Head  has  been 
determined  the  pressure  in  pounds  per  square  inch  is  obtained 
by  multiplying  the  head  in  feet  by  .4335.  The  pressure  in 
pounds  per  square  inch  at  any  given  point  is  equivalent  to  the 
actual  weight  of  a  column  of  water  one  inch  square  and  equal 
in  height  to  the  Pressure  Head. 

PUMPING  HEAD. — The  Pumping  Head  is  the  sum  of  the 
Static  Head  and  the  Friction  Head  necessary  to  discharge  the 
given  quantity  of  water. 

DYNAMIC  HEAD.— The  Dynamic  Head,  or  Head  or  Fall 


PACIFIC  TANK  &  PIPE  COMPANY  13 

actually  used  in  the  production  of  power,  is  the  difference  in 
elevation  between  the  point  of  discharge  and  the  hydraulic 
gradient.  In  connection  with  turbine  wheels  the  discharge 
point  may  be  assumed  to  be  the  elevation  of  the  tail  water 
while  in  the  case  of  tangential  wheels  the  elevation  of  the  center 
of  the  wheel  should  be  considered. 

In  the  design  of  a  pipe  line  for  a  power  system  a  certain 
amount  of  head  is  assumed  to  be  lost,  which  is  made  up  of  the 
sum  of  the  Friction  Head,  the  Entrance  Head  and  the  Velocity 
Head.  The  remainder  of  the  total  head  is  the  actual  fall  of 
water  after  all  deductions  have  been  made  for  the  frictional 
and  other  losses  and  is  the  fall  actually  employed  in  producing 
power. 

WORKING  HEAD.— Working  Head  is  a  term  frequently 
used  and  is  generally  misleading  and  therefore  is  not  here 
defined. 

HYDRAULIC  GRADIENT  OR  HYDRAULIC  GRADE 
LINE. — In  the  case  of  a  pipe  line  having  but  one  intake  and 
one  point  of  discharge,  the  Hydraulic  Gradient  is  a  theoretical 
line  drawn  from  the  surface  of  the  water  in  the  outlet  to  a  point 
in  the  intake.  This  point  is  determined  by  measuring  down 
from  the  surface  of  the  water  a  distance  corresponding  to  the 
sum  of  the  Entrance  Head  and  the  Velocity  Head.  On  the 
basis  of  the  slope  indicated  by  this  line  the  velocity  of  the 
water  is  calculated. 

The  Hydraulic  Gradient  will  be  a  broken  line: 

1. — If  there  be  any  change  in  the  diameter  of  the  pipe. 

2. — If  water  be  drawn  off  at  a  point  or  points  other  than 
the  one  point  above  mentioned. 

3.— If  any  part  of  the  pipe  be  constructed  above  a  straight 
line  drawn  between  the  ends  of  the  pipe. 

This  definition  does  not  cover  the  various  phases  of  the 
Hydraulic  Gradient  and  for  illustration  we  refer  you  to  the 
drawings  on  page  10  and  for  still  further  information  to  the 
various  engineering  text  books  on  the  subject  of  Hydraulics. 


14  PACIFIC  TANK  &  PIPE  COMPANY 

SLOPE.— The  Slope  of  the  pipe  line  is  obtained  by  dividing 
the  Friction  Head  by  the  length  of  the  pipe  line.  This  result, 
in  order  to  obtain  the  basis  on  which  our  table  is  calculated, 
must  then  be  multiplied  by  1000. 

COEFFICIENT  OF  FRICTION  or  COEFFICIENT  OF 
ROUGHNESS.— The  term  Coefficient  of  Friction  as  used  in 
formulae  relating  to  the  flow  of  water  in  pipes  or  channels  is  a 
factor  indicating  the  resistance  due  to  friction  caused  by 
roughness  of  the  surface  in  contact  with  the  flowing  water. 

Were  the  element  of  roughness  entirely  eliminated,  the 
water  would  fall,  by  its  own  weight,  according  to  the  natural 
laws  of  gravity.  The  coefficients  used  in  the  Flow  Tables 
given  in  this  book  have  been  selected  as  representing  as  nearly 
as  possible  the  actual  condition  of  friction  encountered  in 
wooden  pipes.  It  is  well  to  bear  in  mind  that  after  service  of 
a  year  or  two,  the  interior  of  wooden  pipe  is  much  smoother 
than  when  new,  the  amount  of  friction  is  correspondingly  less 
and  as  a  consequence  the  velocity  and  discharge  are  greater. 
On  the  contrary,  the  flow  of  water  in  metal  pipe  never  is  as 
great  as  in  wooden  pipe  and  after  short  service  the  metal 
pipe  tuberculates  and  corrodes  to  such  an  extent  as  to  greatly 
increase  the  friction  and  diminish  the  discharge. 

MEAN  RADIUS  OR  HYDRAULIC  RADIUS.— The  Mean 
(or  Hydraulic)  Radius  is  the  quotient,  in  feet,  obtained  by 
dividing  the  area  of  wet  cross-section  in  square  feet,  by  the 
wet  perimeter  in  feet.  In  pipes  running  full  or  exactly'  half 
full,  and  in  semi-circular  open  channels  running  full,  it  is  equal 
to  one-fourth  of  the  inner  diameter. 

WET  PERIMETER.— The  Wet  Perimeter  is  the  sum  of 
the  lengths,  in  feet,  found  by  measuring  across  the  channel, 
such  parts  of  its  sides  and  bottom  as  are  in  contact  with  the 
water. 

EXAMPLE. — A  channel  3  feet  deep  by  6  feet  wide  with 
water  running  2  feet  6  inches  deep,  has  a  Wet  Perimeter  equal 
to  2  feet  6  inches  plus  2  feet  6  inches  plus  6  feetO inches  =  11  feet. 

The  area  of  wet  cross-section  is  2J^x6  =  15  square  feet.

HYDRAULIC  DATA 

Gallons  per  day  (24  hours)  multiplied  by  .000001547  equals 
Cubic  Feet  per  Second. 

Cubic  Feet  per  Second  divided  by  .000001547  equals  Gallons 
per  day  (24  hours). 

A  Cubic  Foot  of  Water  contains  nearly  7^  gallons  (7.48052) 
and  weighs  about  62J^  pounds. 

A  Gallon  of  Fresh  Water  weighs  8.34  pounds  and  contains 
231  cubic  inches. 

27154  Gallons  of  Water  (3630  Cubic  Feet)  will  cover  one 
acre  one  inch  deep. 

The  Miner's  Inch  has  varying  actual  values  in  different 
states  as  follows :j 

One  Second  Foot  equals  50  Miner's  Inches  in  Utah,  Idaho 
and  Nevada. 

One  Second  Foot  equals  40  Miner's  Inches  in  Montana  and 
Arizona. 

One  Second  Foot  equals  38.4  Miner's  Inches  in  Colorado. 

Note. — The  Miner's  Inch  given  in  the  Flow  Table  in  this 
book,  is  that  generally  spoken  of  as  the  California  Inch,  or 
1/50  of  one  second  foot,  which  is  customarily  used  by  miners 
in  that  State.  The  California  statute,  however,  provides  that 
the  Miner's  Inch  shall  equal  \Yi  cubic  feet  per  minute,  or  one 
second  foot  equals  40  Miner's  Inches. 

One  Acre  Foot  equals  43560  Cubic  Feet  =  one  second  foot 
of  water  flowing  for  12  hours  and  6  minutes. 

Doubling  the  diameter  of  a  pipe  multiplies  its  end  area  four 
times. 

Theoretically  water  can  be  raised  by  suction  33  feet,  but 
practically  only  25  to  28  feet. 

The  amount  of  power  developed  by  water  flowing  through 
a  pipe  may  be  ascertained  by  the  following  formula: 

Horse  Power  =  .1134HS 
in  which  H  equals  the  dynamic  head  in  feet; 

S  equals  the  cubic  feet  of  water  per  second. 

This  gives  a  strictly  theoretical  result  and  from  it  must  be 
deducted  from  20%  to  30%  to  cover  machine  inefficiency. 

Example. — 50  second  feet  of  water  with  75  foot  head: 
75  times  50  times  .1134=425.  Deducting  20%  for  inefficiency 
will  give  340  Horse  Power.

Example  Showing  the  Application  of  the  above  Table. 
Suppose  the  Weir  to  be  60  inches  long,  and  the  depth  of  water 
on  it  to  be  5^  inches.  Follow  down  the  left-hand  column  of 
the  figures  in  the  table  until  you  come  to  5  inches.  Then  run 
across  the  table  on  a  line  with  the  5,  until  under  H  on  top  line, 
and  you  will  find  5.15.  This  multiplied  by  60,  the  length  of 
Weir,  gives  309,  the  number  of  cubic  feet  of  water  passing  per 
minute,  and[this  multiplied  by  7H  will  give  the  gallons — 2317^.

To  find  the  capacity  of  tanks  greater  than  the  largest 
given  in  the  table,  look  in  the  table  for  a  tank  of  one-half  of 
the  given  size,  and  multiply  its  capacity  by  4,  or  one  of  one- 
third  its  size,  and  multiply  its  capacity  by  9,  etc.

RULE.— Find  the  Mean  Radius  of  the  channel  or  flume  by  the  method 
described  under  definitions  of  Mean  Radius  and  Wet  Perimeter. 

Take  from  the  table  of  velocities  the  number  opposite  the  Mean  Radius  and 
under  the  suitable  coefficient  of  roughness.  This  number  must  1  e  multiplied 
by  the  multiple  opposite  the  fall  in  the  table  of  slopes.  The  result  is  the  velocity 
in  feet  per  second. 

The  quantity  of  water  discharged  is  found  by  multiplying  the  area  of  the 
wet  cross-section  by  the  velocity. 

EXAMPLE 

A  box  flume  has  four  foot  straight  sides  and  an  inside  width  of  five  feet, 
the  water  being  calculated  to  run  3.75  feet  deep  with  a  fall  of  1H  inches  per 
100  feet. 

The  wet  perimeter  is  found  to  be  3.75  plus  3.75  plus  5  =  12.5  feet. 

The  area  of  the  wet  cross-section  is  3.75  x  5  =  18.75  square  feet. 

The  Mean  Radius  is  therefor  18.75  ~  12.5  =  1.5. 

Assuming  that  the  coefficient  in  this  case  is  .015.  we  refer  to  the  table  of 
velocities  and  under  .015  and  opposite  1.5  we  find  13.11.  Now  refer  to  the  table 
of  slopes  and  opposite  l}-g"  we  find  the  multiple  .346.  Multiplying  13.11  by  .346 
we  obtain  4.54,  which  equals  the  velocity  in  feet  per  second  of  the  water  in  the 
flume.  The  quantity  of  water  carried  by  the  flume  is  found  to  be  18.75  x  4.54  = 
85.1  cubic  feet  per  second.

TABLES  FOR  FLOW   OF  WATER  THROUGH 
WOOD  PIPE 

In  preparing  the  following  tables  for  the  flow  of  water 
through  wooden  pipes,  such  as  are  manufactured  by  us,  we 
have  given  full  consideration  to  all  of  the  few  tests  that  have 
been  made  from  which  intelligent  deductions  can  be  drawn. 
Unfortunately,  most  of  the  tests  that  have  been  made  were 
with  pipe  constructed  under  unusual  conditions  or  with  greatly 
varying  grades  or  curvature.  It  is  our  intention  to  show  in 
these  tables  as  nearly  as  possible  the  actual  amount  of  water 
that  will  flow  through  wooden  pipes  with  a  minimum  amount 
of  curvature  either  vertical  or  horizontal.  Should  there  be, 
in  a  long  line  of  pipe,  merely  three  or  four  curves  of  considerable 
radius,  the  flow  would  not  be  affected  to  any  appreciable  extent. 

In  preparing  these  tables  we  have  used  the  "Kutter" 
formula  and  a  changeable  value  of  "n."  The  diagram  on  the 
opposite  page  shows  the  various  values  of  "n"  for  all  pipes 
from  2  inches  up  to  168  inches  in  diameter.  It  will  be  observed 
that  the  coefficient  0.011  is  used  for  the  larger  diameters  and 
that  this  valuation  is  slightly  decreased  for  the  smaller  diam- 
eters. Many  engineers  calculate  the  flow  of  water  in  wood 
pipe  with  the  valuation  of  "n"  =  0.010.  We  believe  that  the 
valuation  which  we  have  given  is  safe  and  for  reasonably 
straight  pipes  can  be  used  without  hesitancy. 

We  present  a  few  examples  of  the  use  of  this  table  which 
will  readily  explain  how  the  size  of  pipe  can  be  ascertained  to 
deliver  certain  quantities  of  water,  or  how  with  the  size  given 
the  frictional  loss  can  be  determined;  in  fact,  the  intelligent 
use  of  these  tables  can  be  made  to  do  away  entirely  with  the 
long  tiresome  calculations  that  are  beyond  the  reach  of  the 
layman  and  are  a  tedious  and  complicated  piece  of  work  for 
the  practicing  engineer. 

You  will  note  that  the  first  column  represents  the  loss  of 
head  due  to  friction  in  1,000  feet  of  pipe  when  discharging  a 
given  quantity  of  water.  This  frictional  head  can  be  applied 
to  any  length  of  pipe  by  multiplying  by  the  number  of  thousand 
feet  and  fraction  thereof,  the  result  being  the  total  frictional 

208776 


38  PACIFIC  TANK  &  PIPE  COMPANY 

loss  in  the  entire  pipe.  The  second  column  shows  the  mean 
velocity  in  feet  per  second,  an  item  which  is  rarely  considered 
by  the  layman.  The  third  column  is  the  discharge  of  the  pipe 
in  cubic  feet  per  second.  The  fourth  gives  the  discharge  in 
gallons  per  minute  and  the  fifth  gives  the  discharge  in  miner's 
inches.  The  miner's  inch  used  herein  is  equivalent  to  one- 
fiftieth  of  a  cubic  foot  per  second. 

In  the  last  column  is  given  the  combined  entrance  and  ve- 
locity heads.  This  figure  represents  the  head  of  water  which 
should  stand  over  the  top  of  the  pipe  at  the  intake  in  order  to 
give  the  body  of  water  in  the  pipe  the  velocity,  and  conse- 
quently, the  discharge  required.  This  item  can  be  reduced 
nearly  one-third  provided  that  the  intake  end  of  the  pipe  is 
enlarged  so  as  to  eliminate  the  entrance  friction.  (See  definition 
of  Entrance  Head.) 

EXAMPLES 
1.     Pipe  to  be  used  as  an  Inverted  Syphon. 

[Size  of  pipe 60  inches. 

Given] Length  of  pipe.  .  .3200  feet. 

[Discharge 286  cubic  feet  per  second. 

Required— Total  Head. 

Turning  to  the  table  showing  a  diameter  of  60*  we  find 
opposite  the  discharge  of  286  cubic  feet  per  second,  that  8  feet 
of  head  is  required  for  friction  in  each  1000  feet  of  pipe.  The 
friction  in  the  entire  line  is  therefore  found  by  3.2x8  =  25.6 
feet.  Glancing  across  the  same  line  from  which  we  obtained 
the  friction  head,  we  find  that  4.9  feet  is  required  for  velocity 
and  entrance  head.  This  added  to  25.6  equals  30.5  feet,  which 
is  the  Total  Head  required  to  discharge  the  given  quantity  of 
water. 

Should  occasion  occur  in  which  the  exact  discharge  required 
is  not  found  in  the  table,  the  friction  head  as  well  as  the  velocity 
and  entrance  heads  can  be  determined,  sufficiently  close,  by 
comparison  with  adjoining  discharges  and  heads  either  by  the 
eye  or  by  simple  proportion. 

Should  the  quantity  of  water  given  be  stated  in  gallons  per 
minute  or  in  miner's  inches,  the  calculation  would  be  effected 
in  the  same  manner. 


PACIFIC  TANK  &  PIPE  COMPANY  39 

2.  Pipe  to  be  used  as  an  Inverted  Syphon. 

(Length  of  pipe 4800  feet. 

Given]  Discharge 92  sec.  feet. 

[Total  Head 36.2  feet. 

Required — Size. 

As  part  of  this  Total  Head  will  be  taken  up  as  velocity  and 
entrance  head,  until  we  know  the  exact  velocity,  we  can  obtain 
only  an  approximate  result.  We  therefore  proceed  to  divide 
the  Total  Head  by  the  number  of  thousands  of  feet  of  length: 
36.2  divided  by  4.8  equals  7.5  plus.  Now  let  us  assume  that 
the  .5  feet  will  be  devoted  to  velocity  and  entrance  head  and 
the  7  feet  to  the  friction  head  in  1000  feet  of  pipe.  Referring 
to  the  table,  and  after  examining  several  pages  we  find  that 
under  a  diameter  of  40  inches  and  opposite  7  feet  is  the  required 
discharge,  namely  92  sec.  feet.  We  now  multiply  for  the  exact 
friction  head:  7x4.8  equals  33.6  feet.  To  this  add  2.6  for 
velocity  and  entrance  head,  giving  a  total  of  36.2  feet.  40 
inches  is  therefore  the  diameter  required.  In  this  example,  it 
is  sometimes  necessary  to  make  several  trials  before  the 
correct  result  is  obtained. 

3.  Pipe  to  be  used  as  an  Inverted  Syphon. 

f  Size 20       inches. 

Given]  Length 4260       feet. 

[Total  Head 22.16  feet. 

Required — Discharge. 

Divide  22.16  by  4.26  equals  5  plus.  Assuming  the  friction 
head  to  be  5  feet,  the  total  friction  head  will  be  5  multiplied 
by  4.26  equals  21.30.  To  this  add  velocity  and  entrance  head 
.86  feet  equals  a  total  head  of  22.16  feet.  From  the  table  op- 
posite a  friction  head  of  5  feet  per  1000  it  is  found  that  the 
discharge  is  13.3  sec.  feet,  the  answer  sought. 

4.  A  pipe  supplying  water  for  a  Power  Plant. 

The'size  of  pipe,  the  discharge  and  the  friction,  velocity  and 
entrance  heads  may  be  determined  as  shown  above  but  it 
must  not  be  forgotten  that  the  dynamic  head  is  the  important 
factor  to  be  considered.  From  this  alone  power  is  developed. 
An  increase  in  pipe  diameter  means  less  friction  head  and  more 
dynamic  head  and  consequently  an  increase  in  the  number  of 
horse  power  developed. 


40  PACIFIC  TANK  &  PIPE  COMPANY 

The  economic  size  of  pipe  to  employ  should  be  given  the  care- 
ful study  of  a  capable  engineer. 

5.    A  pipe  used  as  a  Pumping  Line. 

In  pumping  from  a  source  of  supply  to  a  reservoir  or  ditch 
the  water  may  be  assumed  to  be  lifted  straight  up  in  the  air 
to  such  a  height  that  it  will,  by  gravity,  flow  to  the  point  of 
discharge.  For  example,  a  pump  is  required  to  lift  3000  gallons 
per  minute  through  3500  feet  of  16*  pipe  to  a  reservoir  having 
its  water  surface  43  feet  above  the  pump.  Referring  to  the 
table,  it  is  found  that  in  discharging  3000  gallons  per  minute 
through  a  16"  pipe,  there  is  4  feet  of  friction  head  per  1000 
feet  of  pipe,  or  4  multiplied  by  3.5  equals  14  feet  in  the  entire 
line.  The  pump  will  therefore  be  compelled  to  work  against 
a  pumping  head  of  43  feet  plus  14  feet  equals  57  feet. 

The  diameter  of  pipe  selected  is  governed  largely  by  the 
cost  of  pumping  and  the  experienced  engineer  should  be  called 
upon  for  an  economic  consideration  of  the  subject.
